Predicted to enable erythropoietin receptor activity and identical protein binding activity. Acts upstream of or within animal organ development and signal transduction. Predicted to be located in cytoplasm; external side of plasma membrane; and nuclear speck. Is expressed in several structures, including brain; egg cylinder; genitourinary system; germ layer; and heart and pericardium. Human ortholog(s) of this gene implicated in anemia; familial erythrocytosis 1; high grade glioma; polycythemia; and systemic lupus erythematosus. Orthologous to human EPOR (erythropoietin receptor).
